摘要

水土保持自然生态修复作为生态建设的一项主要任务,需要进行水土保持生态修复适宜区研究。论文以陕西省为例,应用ArcGIS 9.2空间数据分析工具,综合分析土地利用类型、年降雨量、土壤侵蚀、人口密度等指标,划分出陕西省水土保持自然生态修复适宜区域,并分析了陕西省水土保持综合治理实施情况。结果表明,陕西省水土保持自然生态修复区面积为23 911 km²,秦岭大巴山区适宜自然生态修复的面积最大,研究为水土保持综合治理下一步实施提供借鉴意义。

Abstract

Study on system consideration and suitability on soil and water conservation are important factors on natural ecosystem restoration. This study combined spatial data analysis tool ArcGIS 9.2 and comprehensive evaluation method to analyze ecosystem restoration situation in Shaanxi Province. Land type, soil erosion, average annual rainfall and population density were selected as soil-and-water-conservation-based natural ecosystem restoration indexes, to indentify areas suitable for ecological rehabilitation in Shaanxi Province. Through analysis of comprehensive implementation on soil and water conservation in Shaanxi, the result showed that artificial administrative areas occupied over 80% of the county areas, but natural banned management area ratio was small. After comparatively analyses of those parameters on ecological rehabilitation for comprehensive treatment of soil and water loss, several results were concluded: the area suitable for natural restoration in Shaanxi Province was about 23911 km²; the most suitable area for natural ecosystem restoration was in Qinling-Daba Mountains, however, it is necessary to strengthen natural ecosystem restoration efforts at regional level.
